* Permissible limits of the voltage range at which the unit operates satisfactorily.

#Unit ampacity = 125 percent of largest operating component’s full load amps plus 100 percent of all other potential operating components’ (EAC, humidifier, etc.) full load amps.

† Time-delay type is recommended.

‡ Length shown is as measured 1 way along wire path between unit and service panel for maximum 2 percent voltage drop. ** Preliminary

Furnace control must be grounded for proper operation or control will lock out. Control is grounded through green/yellow wire routed to gas valve and manifold bracket screw.

115-V WIRING

Verify that the voltage, frequency, and phase correspond to that specified on unit rating plate. Also, check to be sure that service provided by utility is sufficient to handle load imposed by this equipment. Refer to rating plate or Table 5 for equipment electrical specifications. Make all electrical connections in accordance with National Electrical Code (NEC) ANSI/NFPA 70-2002 and any local codes or ordinances that might apply. For Canadian instal- lations, all electrical connections must be made in accordance with Canadian Electrical Code CSA C22.1 or authorities having juris- diction.

TWO

A02099

Do not connect aluminum wire between disconnect switch and furnace. Use only copper wire.

Use a separate, fused branch electrical circuit with a properly sized fuse or circuit breaker for this furnace. See Table 5 for wire size and fuse specifications. A readily accessible means of electrical disconnect must be located within sight of the furnace.

NOTE: Proper polarity must be maintained for 115-v wiring. If polarity is incorrect, control LED status indicator light will flash rapidly and furnace will NOT operate.

J-BOX RELOCATION

NOTE: If factory location of J-Box is acceptable, go to next section (J-Box Cover Installation).

NOTE: On 14″ wide casing models, the J-Box shall not be relocated to other side of furnace casing when the vent pipe is routed within the casing.

1.Remove screws holding auxiliary J-box. (See Fig. 22.)

2.Cut wire tie on loop in wires to J-box.

Fig. 22—Relocating J-Box

3.Locate box to desired location.

4.Fasten J-Box to casing with screws.

5.Route J-box wires within furnace away from sharp edges and hot surfaces.

ELECTRICAL CONNECTION TO J-BOX

If manual disconnect switch is to be mounted on furnace, select a location where a drill or fastener will not contact electrical or gas components.

1.Attach electrical box to J-Box bracket.

2.Route wires through hole in electrical box and J-Box bracket.

3.Secure ground wire to green screw on J-Box bracket.

4.Connect line voltage leads as shown in Fig. 24.

FOR POWER CORD INSTALLATION

Power cords must be able to handle the electrical requirements listed in Table 5. Refer to power cord manufacturer’s listings.
